PROJECTING-MAGHINE.

Specification of Letters Patent.

I Application filed June 2, 1913. Serial No. 771,147.

I a machine by the use of ditl'ractors, which will, with a continuous moving film, correctly focus the picture atall times upon a screen.

The invention consists, as shown in the special embodiment illustrated by the drawings in this case, of n'ieans for moving a picture film continuously across the light rays from an arc lamp or other light emitting source, and providing for such picture a 'moving plate having eccentric slots thr ugh its surface and moving with a definite relation to the movement of the film, so that as the film moves downwardly the slot will also have moved eccentrically to always keep said picture framed in the slot between for its two horizontal lines, and upon the coinplete passage of the picture out of the line of projection the next succeeding picture will come under the intluence of a second eccentric slot, whereby the projecting =of the second picture will follow the first, and

so on.

In order to have the light rays properly follow the moving tihnfl prefer to provide a ditl'ractor for directing the concentrated rays of light from the arc, and causing them to travel through the ditfractor with a change of direction of such extent as to follow the moving picture in its travel which is to keep good light and perfect focus as well as conserving the light. At the completion of the travel of onepicture auto- .u'iaticmeans are provided for changing such light ditl'ractor to operate upon the next picture in its new position, The rays of light which pass through the picture, and through the lens, must also be corrected with relation to the screen, so as *0 always pass through the lens in the same position. and asecoud importantfeature is that the distance between the picture and the lens must be maintained the same for the'light rays, or any deviation due to the use. of ditl'ractors, must be compensated. To accoinplish this purpose between the picture and the lens, I 4

provide twin ditfractors, both operatively connected, and moving in unison with the light di'tfractors before-mentioned, and the eccentric slots and film. One of these dif fractors is adapted to act in connection with the moving picture, so that all the light which passes thercthrough will be changed in direction, so that upon the screen there Will be the appearance of a stationary picture, although the fi-hn is moving. The first dilfractor is similarly actuated, and for the purpose of this case, I will call it the compensating diffractor. It is so connected with its twin difi'ractor, that at all times they will occupy an angle with relation to each other such that the diffraction of the.

rays by one will be corrected by the other, as to the distance between the picture and the lens, so that perfect focus may be maintained in this type of apparatus, which has heretofore been impossible.

Flllt'llQllllOl'G in carrying out the invention as above set forth I operate the slotted plate, the ditl'ractors, the film, all from a common shaft. The common shaft through a sprocket tends to move the picture film through the machine, to rotate by gearing the plate with the slots, which is mounted on the shaft itself. A cam is carried by the plate for operating mechanisms for operating the difi'ractors.

The scope of my invention will be pointed As shown in the drawings: 1 is the frame.

provided with an aperture for the lens L, shown diagramnlatically in the picture. The frame is also provided with bearings 20 and .21 for a shaft 23. which shaft carries a beveled gear 9 meshing with a beveled gear 10 on a shaft- 11, on which the sn'ockee reel 12 is mounted. so that upon the rotation of the shaft the sprocket reel will be continuously operated. On the shaft 23 a plate 2 with concentric openings is mounted, se-
